Horrible Service

please can you add a minus star for the poor service i have received especially from VOX the installation was done on the 20th of May and did not work i called vox the very same day and the troubleshooting was done a ref number was issued VOX*** i did a follow up on 26th of May apparently what was installed was not communicating with the frogfoot box outside a technician from frogfoot was supposed to come and check what the problem was i then received a bill to pay for wifi that i have never used, i then received another bill to pay for the supposedly free installation now im expected to pay R3363 and was threatned that if i dont pay it they will find ways to collect it..collect for a service that i have never received this is the worse service ever i have called Vox a numerous times to try and resolve this issue but no amicable solution has been reached all i am receiving is statements asking for payment from me, the lady that signed me up is telling me that she has moved from the sales department to marketing and she gave me the number to call i think i am passed a stage of calling Vox
